So was I.
The trick is that if you request a passive socket from getaddrinfo, it
should return a list of sockets that should *all* be bound.
So on stock linux, a AI_PASSIVE request for a wild card adress on a v6
capable kernel will return only a wild card v6 address.
On a USAGI system (bsd et al) AI_PASSIVE for a wild card address will
return v4 and v6 wildcards which must both be bound.
This hides the functional difference behind the standard interface and
lets everything work nicely.
